To all whom t may concern.

lle, it known that l, 'lnoMAs F. l. tllBRmN, a citizen ot' the Unit/ed States, residinoat Brooklyn` in the county of ltings and @ta-te ot New York, have invented certain new and useful Improvements 1n tlosures for Receptacles; and l do hereb),1 declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates more particularly `to receptacle closures such as are applied to bottles and jars, etc., and is ot the typev which ma be removed and replaced at will.

The objects of the invention are to provide a receptacle closure of this type which will be secure, but which may be readily manipulated both to apply and remove it; to obtain al structure which will resist internal pressure from the container; to provide a structure adapted to various sizes and makes of containers; to employparts which may be readily manufactured with minimum operation and material; to posia tively hold the cap in place; to prevent the parts from becoming separated; to secure simplicity of construction and manipulation, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawing in which like numerals of reference indicate similar parts throughout the several views;

Figure l is a perspective view of my improvedrclosure in operative position upon a bottle; v

Figure 2 is a perspective view showing the closure removed ytrom the bottle;

Figure 3 is'a cross sectional view of the same taken u on a diametric plane through the middle otlp an opposite pair of jaws, and

Figure 4L is a perspective View of the invention as applied to a jar.

ln the specific embodiment of the invention illustrated in said drawing the reference numeral l indicates in general the receptaole closure, which comprises a top or body 2 around the circumference of which are depending jaws 3 adapted to be clamped inwardly by means ot a ring 4f. As' shown in yFigure l the receptacle closure is adapted to be positioned upon the bottle 5, the bottle having a downwardly lacing shoulder 6 near` its mouth as is common with rbottles now'npon the market.- 'lhe closure is proportioned so as to over-lie the mouth o f the bottle and with its jaws 3 substar1- 60 tially the same length as'the distance ot said shoulder from the mouth of the bottle. ln other words, the jaws 3 will depend to substantially the plane of said shoulder 6. As shown clearly in Figures 1 to 3 the jaws 65. are provi-ded with inturned lips 7 on their lower ends adapted to underlie said shoull der and prevent the closure from coming ott ot the bottle. Freferably jaws 3 are of resilient metal so they will normally 7o spread apart or open as shown in Figures 2 and 3 to permit the closure to be applied to or removed from the bottle. After the closure is applied the ring l is slid downwardly, pressing the jaws toward each other and causing the lips 7 to engage under the shoulder 6. So long as the ring remains slid down the closure `will be very securely held against withdrawal, but ob viously the user may very readily slide the 8o rin upwardly and then remove the closure wit out dilliculty.

ln order to prevent the ring from being slid od the jaws,-l have shown tabs or ears 8 projecting outwardly from the body 2 at g5 intervals around the same far venough to over-lie the ring and engage the same when it ispushed up to that position, as clearly shown in Figure 2. By preference these tabs or ears 8 are formed from metal in 90 the plane of the body 2 between the jaws 3, and in this way the entire oap may be nia-de ot one piece ot material stamped out with a minimum number of operations and thus are not only easily manufactured but are also cheaply manufactured because of the minumum operations and material, and also have maximum strength and durability.

lf it is found desirable the jaws 3 may have wedge like protuberances 9 near their 100 bottom ends, said protuberances being ar ranged and adapted to be engaged by the ring t as it is pressed down which will accordingly exert greater inward pressure upon the jaws tor securely clamping them los toward the receptacle. lt may also be noted that these protuberances also serve an additional function in that they more positively prevent the ring t from being slid down so lar as to come ont the jaws, mit although it will lbe understood that the tendency of the jaws to spread apart is ordinarily suflicieut to keep the ring from comingr ofi'.

It is to be understood that the present invention may be constructed of various shapes and in various sizes and for cylindrical shaped receptacles it is preferable to` have the closure conformed of similar shape and for that reason the jaws 3 have been shown curved and the lips 7 similarly curved at their inner edges to obtain engagement upon the shoulder 6 for their entire length. It is to be understood, however, that this may be varied and the cap made otherwise in this respect without departing` from the spirit or scope of the present invention.

Obviously, for larger receptacles a ,greater number of jaws may be employed. and for purposes of illustration the invention has been shown applied in Figure 4 to an open mouthed jar or jelly glass 10, the closure being otherwise substantially as-described except for the increase of size and also the increase in number of jaws. Other detail modifications and changes may be made in the manufacture and use of my invention. and l do not wish to be understoml as restricting myself except as recited iu the followingr claim When construed in the light of the prior art.

HavingA thus described my invention` l clailnz- A closureI for bottles or thel like compris ing a circular body member having a plurality ot radially extending legs, alternate legs being` relatively long with respect to those next adjacent` the relatively short legs lying in the same plane with the body the relatively lonrer legs being bent adjacent the circumference of the body part into planes oblique to the body and being provided adjacent their outer ends with outwardly project-ingcam parts and inwardly directed gripping* parts, and a ring member surrounding said relatively long' legs and between said relatively short legs and said cam parts, substantially as speciicd.

n testimony whereof l aflix my signature.
